Hi,
For compatibility reasons (work with Biopython) I would like to use to
Numeric in some code of mine. (Of course, I could make a little detour
converting into numpy.array, but first I wonder whether somebody might
know a solution for the problem with Numeric.)
I need to flatten a simple 3x3 array and try to do that with resize.
First time works, next time it doesn't. Here is an example:
In [1]: from Numeric import *
In [2]: a = array([[ 0.50622966, -0.54764389, -0.66619644],
[ 0.44338279, -0.4973092, 0.7457228 ],[-0.73969131, -0.67288704,
-0.00893311]])
In [3]: a.resize((9,))
Out[3]:
array([ 0.50622966, -0.54764389, -0.66619644, 0.44338279, -0.4973092 ,
0.7457228 ,
-0.73969131, -0.67288704, -0.00893311])
In [4]: a.resize((9,))
---------------------------------------------------------------------------
<type 'exceptions.ValueError'> Traceback (most recent call
last)
/home/cm/Documents/projects/SAXS/Eury/MC_rigid/<ipython console> in
<module>()
<type 'exceptions.ValueError'>: cannot resize an array that has been
referenced or is referencing
another array in this way. Use the resize function.
Unfortunately, when applying resize on the actual array I have, I get a
similar, yet slightly different error:
Traceback (most recent call last):
File "sym_get.py", line 37, in <module>
s.inquire_relation()
File "/usr/lib/python2.5/site-packages/mc_saxs/mc_rigid.py", line 915,
in inquire_relation
print rotation, rotation.resize((9,))
ValueError: resize only works on contiguous arrays
The arrays 'a' and 'rotation' are identical.
Any ideas, what's going on or how to solve this?
Numeric version is: 24.2
TIA
